Title: Connecting mechanism for compressor
Inventor: NISHIZAWA KAZUTOSHI
IPC: F04B35/00
Filed: 1986-11-27
Abstract: PURPOSE:To reduce the load on starting a compressor and permit the smooth start by preventing the hydraulic pressure in a pressure chamber from being introduced into a control pressure chamber before a piston is shifted by the hydraulic pressure supplied from an oil pump. CONSTITUTION:A piston 220 for shifting the clutch plates 320 and 330 of a connecting mechanism and a bypass valve 540 for opening and closing the variable capacity type bypass port 520 of a compressor 600 are controlled by the hydraulic pressure supplied from a same oil pump. In other words, the hydraulic pressure supplied from an oil pump 201 is introduced into a pressure chamber 225 on the back surface of the piston through an introduced oil passage 228, and introduced from the pressure chamber 225 into a control pressure chamber 550 on the back surface of a bypass through a signal passage 351. With such constitution, the load on starting can be reduced, and the smooth start of the compressor is permitted.

A gap is created between the heat-insulating ring 2 and the nozzle by preparing the heat-insulating ring 2 as the separating body from the nozzle, and the heat-insulation is improved and the heat shock developed at the molten metal hitting part and in the vicinity thereof is once hindered with the heat-insulating ring 2 and the development of the longitudinal crack and the other crack in the nozzle caused by the rapid temp. gradient is prevented.  The material of the heat-insulating ring 2 is desirable to have lower heat conductivity than that of the nozzle body 1, but since the heat-insulating effect of a little gap is produced, even the same material as or the one having higher heat conductivity than that of the nozzle body 1 can be used.

Title: Power source for magnetron
Inventor: HOSHINO HIROYUKI
IPC: H05B6/68
Filed: 1988-11-10
Abstract: PURPOSE:To shorten starting time of a magnetron by controlling a switching device of an inverter circuit with frequency responding to an output of anode current detection of the magnetron. CONSTITUTION:At the time of immediate after power load, magnetron 12 does not oscillate and an output voltage of an anode current detection through a current transducer 13 becomes small as compared to a reference voltage of a reference circuit 18 and a first comparator 21 is turned on and an output of a comparison circuit 29 becomes the minimum value set by a lower limiter. By this, a pulse duration of output generated by a PWM circuit 33 becomes narrow and a driving circuit 34 is turned on within a short time by a trigger frequency of a high frequency responding to a detection anode current and cathode current is controlled. Then, when the cathode is warmed up and the magnetron is in a state to oscillate normally, the anode current becomes large, the comparator is turned off, and output of the circuit 29 is automatically set in the prescribed value by an upper limiter. Minimum output for a prescribed period is thus not needed and starting time of the magnetron is shortened.

Abstract: PURPOSE:To enable highly precise trimming by trimming a thin-film resistor horizontally with electric currents, from the end nearest to the electrode wiring layer of the trimming land of a thin-film resistor at the first stage, and from the end farthest from the electrode wiring layer at the second stage. CONSTITUTION:A voltage across both ends of a thin-film resistor at a first stage is measured while constant currents are supplied to a thin-film resistor 1 from the constant current source connected to an electrode wiring layer 2 glued to a part of the thin-film resistor. Next, while observing indicated values of a voltmeter 4 with the current from the constant current source 3 remained constant, a cut 5a is made horizontally to currents from the end most near the electrode of the trimming land of the thin-film resistor by letting a value a little smaller than the required voltage value to be a tentative required voltage at the first stage. When the value of the voltmeter becomes the tentative required voltage, trimming is terminated temporarily. Then, a cut 5a is made horizontally with currents from the end far from the electrode of the trimming land of the thin-film resistor. When the scale of the voltmeter becomes the required value, trimming by laser beam is terminated.
